Page 1 of 14 ***Ball Mill Explosion!*** posted in Safety: I just got off the phone with Burrito Bandito, he is in the hospital with some second degree burns and is missing his right pinky finger when his ball mill jar exploded late on the 4th of July when he was tending the jar after it caked up on him. BB was using glass marbles as his grinding media and a Harbor Freight rock tumbler
Hammer mills are often engineered to be strong enough to contain a dust explosion, but sparks or smoldering particles may spread from the mill to other more vulnerable equipment. Associated cyclone/dust collector units are not as strongly constructed, and should be equipped with explosion relief and a rotary valve at the discharge.
A dust explosion is the rapid combustion of fine particles suspended in the air within an enclosed location. Dust explosions can occur where any dispersed powdered combustible material is present in high-enough concentrations in the atmosphere or other oxidizing gaseous medium, such as pure oxygen.In cases when fuel plays the role of a combustible material, the explosion is known as a fuel

Associated cyclone/dust collector units are not as strongly constructed, and should be equipped with explosion relief and a rotary valve at the discharge.
The power failure forced the mill out of operation, which caused gas to build up in an on-site pulp digester. That is what officials believe ultimately caused the explosion. The company's preliminary findings released March 9 show that when the digester was out of operation for an extended period of time, the gases built up and created an “explosive atmosphere.” Again, there were not any

Explosion pressure detectors are mounted both on the mill and the receiver. They detect the pressure excursion from an impending explosion. Infrared detectors are also a common detection means for mills utilizing pneumatic conveying of the ground material. The detectors transmit a signal to a control panel, which triggers high rate discharge extinguishers while simultaneously shutting down the

The worst stone mill explosion on record occurred in Westwego, Louisiana in 1977, when a buildup of stone dust came in contact with static electricity. The explosion caused 49 silos to catch fire, killing 36 workers, many from being crushed by the collapsing silos. Building code reforms for stone silos were based off this event. In 1981, there was a dust explosion at the Bird’s Custard

The risk assessment has also to consider the organisation of the company, any individuals identified as being particularly at risk and the fire or explosion measures already in place. It has to be concluded whether these measures are sufficient or would need changes and improvements. The implementation may mean making changes to the organisation and working procedures, working environment
Risk-based: Risk-based analysis is used to estimate the risk associated with a process and determine if the associated risk is acceptable, in accordance with industry and societal accepted levels of exposure. This method is best suited for companies that have many of the same types of equipment operating in similar conditions, since the rigor and engineering effort to develop a risk-based DHA
Dust Explosion Prevention A dust cloud of flammable concentration can be produced in industry either by design or by chance. For example, lean-phase pneumatic transfer systems handling flammable dust have an almost continual dust cloud present. In processes such as the filling and emptying of dust containers a dust cloud of flammable concentration is produced transiently.

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles and stainless steel balls.
